' Application filed March 26,1907. Serial No. 364,610.

To all whom it may concern:

Be it known that I, OTTO CAESAR, a citizen of the United States, and a resident of the I and Improved Window-Cleaner, of which the following 1s a full, clear, an'd'exact descrip tion. a

The object of the invention is to provide a new and improved window cleaner, arranged to permit convenient and thorough cleaning of the window sash, both on the inslde and outside, and without the slightest danger to the operator.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinframe after and then pointed out in the claims.

A practical embodiment of the nvention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the improvernent as applied; Fig. 2 is a longitudinal section of Fig. 1; Fig. 3 is an'enlarged inverted plan view of the improvement, npart being shown in section; Fig. 4 is an e ar'ged seetional side elevation of the outer wiping device; Fig. 5 is a front view of the inner wiping device,-and Fig. 6 is a transverse section of the improvement on the line 66 of Fig. 3.

The main frame A of the window cleaner is U-shaped and consists of the middle bar A. and the side arms A, A ada ted to straddle the window sash B, as pla' y'illustrated in Figs. 1 and 2, that is, the side arm A extendin on the outside of the window sash, while t e side arm A is on-the inside of the window sash, and the cross bar A is arranged transversely below the bottom of the partly open sash. The middle bar A of the main A is provided at itsends with trunnions A enga g a bearing 0 mounted to slide on a rod extending between the sides of the window frame B, and provided at its ends withangular arms D, D having longitudinally extendin trunnions D, D adapted to engage keepers and E, referably in the form of sockets, secured to t e parting strips -B on the sides ,of the window frame B, as

lainly indicated in Figs. 1 and 2. Now by ha the angular arms D, D the rod D may e readily'brought directly under the lower sash, as indicated in Figs. 1- and 2; or

the rod may be swung outward, so as to bring the same directly under the upper sash, as indicated in dotted lines in Fig. 2. Thus by the arrangement described, the device can be brought into proper alinement with the lower sash when it 1s desired to clean the latter, as hereinafter more fully described.

The outer or free end of the side arm A of the main frame A is provided with a bearing for the transverse pivot F of a swing arm F, and the outer end of the side arm A of the main frame A is provided with a bearing for the transverse pivot G ofa'swing arm G,'the swing arms F and G being provided with wipers H and I adapted to engage the glass pane of the window sash, to wipe, rub and clean the same both at the inside and outside of the window, andfsimultaneously, if desired.

Now in order to actuate the outer swim arm F in unison with the inner swing arm controlled by the operator, the pivotal ends of the swing arms F and G are provided with drums orgrooved pulleys J and J, on which winds a ca le, rope or like flexible connection K, also passing over a set of tension pulleys K held on the side arm A and over sets of guide pulleys K K and K, K journaled on the cross bar A of the main frame A, adj acent to the corresponding side arms A A The ends of the cable K are rigidly secured to one of the drums J or J, so as to ractically render the cable endless, and by mounting the tension pulleys K on a frame K held adjustably on the side arm A it is evident that the desired tension can be given -to the cable K, and hence when a swinging motion is given to the swing arm G then the cable K is caused to travel. and to impart a like swinging motion to the swing arm F, so that the latter moves in unison with the swing arm G.

, Now inorder to manipulate the device a simultaneous swin ing motion is given by the operator to t e side arm A and the swing arm G, which are both rovided for this purpose with suitable hand es L and L, adapted to be taken hold of by the operator with both hands. Now on swinging the main frame A and at the same time im arting a simultaneous swin ingmotion to oth swing arms G and F, it is evident that each and every part of the pane of the window sash can e reached by the wipin devices H and I, in order to clean the same oth at the inside and outside. The swing arm F is prefof the window sash.-

erably made in the form of two tubes, in the .outer ends of which telescope the rods H,

H are connected with each other by a socket H for removably receiving the angular frame H su porting a body plate H of sheet metal or a l' e material, and inclosed in a pocket H made of a suitable fabric material for en agement with the window pane. The ody plate H as well as the covering H are approximately of triangular shape, as indicated in Fig. 1, so as 'to ermit of conveniently reaching and thoroughl cleaning the corners he ocket H is held removably on the body p ate H and it is readily secured in lace on the body plate by buttonin it to a utton H, as indicated in Fig. 4. he angular frame H is provided with a spring'tongue H1 adapted to snap under a cross bar or keeper H held on the socket H", to hold the wiper H against displacement, at the same time ilermitting the removal of the wiper from. e socket H whenever it is desired to chancge the same.

The swing arm G is likewise ma e of a air of tubes into which telescope the rods (see Fig. 5), the rods 1' terminatin at their outer ends in a loop I having a catc Iifor receiving and holding an arm I fulcrumed on a cross piece I connectin the rods Iwith each other. A sprin Ihel on the cross piece I presses the arm 4 in an inward direction, and

. the said arms I are providedwith a socket I for removably sup orting a spring frame I carryinga body p ate similar to the body plate H and covered by a covering I similar to the cover H The fraime I is also provided with-a s ring tongue 1 similar to the s ring tongue fl, so that further description 0 the same is not deemed necessary. Now by the arrangement described the wiper I is pressed into engagement with the inside of the window pane by the action of the spring I", and whenever it is desired not to make use of this wiper I it is only necessary for. the operator to swing the arm 1 outward and engage the same with thespringcatch I to hold the wiper in an inactive position, as indicated in dotted lines in Fig. 3. It is evident, however, that when the wiper is in its inactive potion, the arm G and frame A are manipu lated in the same manner as previously mentioned, so as to cause the outer wiper H to clean the outer face of the window pane whenever it is desired to do so.

It will also be noticed that by the o erator moving the bearing ,0 lengthwise on t' e supporting rod D and swinging the frameA as retractable trunnion 13 (see Fig. 3) the supporting rod 1) can be readily enga ed with or disengaged from the keepers E, 15, to allow ready use of the device on any window, and

to permit convenient disengagement of'the devicefrom one window and transferring it to another window. I

In order to prevent a too easy sliding of spring G maybe employe attached to the bearing 0 and (pressing on the supporting rod 'the bearing 0 on the supporting rod D, a

conveniently manipulates the device, to

readily clean the w ndow pane both at the inside and outside, without the slightest danger to the operator.
